| Abstract: | In this paper, the actuality and the common algorithm of the chart linear feature automatic generalization were analyzed. The concept and the definition of the double direction buffering algorithm were introduced. Then the characteristics of the double direction buffering algorithm were studied and proved. The principle of generalizing the chart linear feature was analyzed based on double direction buffering algorithm, and the advantages of the double direction buffering algorithm to the common algorithms, such as the perpendicular distance algorithm, was compared. Experimrntal result indicated that it was feasible to decide the buffering radius with these methods. |
